I want to join these together so I purchased a license as the IBM's dont come or allow you to just connect the 2 switches together and merge the fabrics etc.

so I completely remove all running configuration of one and made sure its domain Id was set Higher number than the current "Principal"

I also set on the principal switch the "set as preffered principal switch" and set value to one

On the blan other switch I made domain ID 10 and switch priority as 30.

Plugged in a cable and an E port formed fine no issue or errors..But the principal switch did not copy its zone config or anything down to the completely blank switch.

In trying to figure this out I looked at the license they have sent me and it says "Extended fabric feature" which when reading is if you want to extend your fabric's very long distance ....which I dont as both swicthes in same rack.

The only thing not happening is the copy of the zone and configuration info.

Re: ISL question.

I think what you need is a "Full Fabric" license for all of your switches.

The full fabric license enables the switches to cascade and therefore to distribute the zone config. The "Extended Fabric" license you need only on distances larger than 10 km between your switches.

For cost reasons in ROBO-environments there used to be a Base-version of the Brocade 8/24 without the full fabric license. As long as you have only one switch per fabric this is ok. But if you want to connect another switch, you need the license on both sides of your ISL. I don't know the IBM OEM version, so check the license information on all your switches.
